FileIOPermission^ rootFilePermissions =
   gcnew FileIOPermission( PermissionState::None );
rootFilePermissions->AllLocalFiles = FileIOPermissionAccess::Read;

namedPermissions->AddPermission( rootFilePermissions );

// Create a PolicyStatement with exclusive rights to the policy.
PolicyStatement^ policy = gcnew PolicyStatement(
   namedPermissions,PolicyStatementAttribute::Exclusive );

// Create a FirstMatchCodeGroup with a membership condition that
// matches all code, and an exclusive policy.
FirstMatchCodeGroup^ codeGroup = gcnew FirstMatchCodeGroup(
   gcnew AllMembershipCondition,policy );
